FIELD CAPACITY OF SILT LOAM AND CLAY LOAM SOILS IS APPROXIMATELY
35 PERCENT OF VOLUMETRIC SOIL MOISTURE. THE PLANT AVAILABLE WATER
OF THESE SOILS IS AVAILABLE TO PLANTS AT VALUES BETWEEN 13 AND 45
PERCENT. TO APPROXIMATE PLANT AVAILABLE WATER AS LISTED IN THE NEXT
SECTION...DIVIDE THE LISTED VALUE BY 40 AND MULTIPLY BY 100. FOR
EXAMPLE...30/40 TIMES 100 EQUALS 75 PERCENT. VALUES GREATER THAN
50 INDICATE VERY MOIST SOIL CONDITIONS.

SOIL MOISTURE /CENTIBARS/ AT LISTED DEPTH
VALUES ARE IN CENTIBARS. 200 CB IS DRY...0 IS WET.
